If you run:
while true; do cygcheck -cd cygwin > /dev/null; done
for one day or so, you will find the issue can be reproduced.
Both cygwin-3_4-branch and main (master) branch have this issue,
while cygwin 3.3.6 does not.

Errors seem to be three types: (null), cygpid.xxx and shared.5.
I'm not sure what is happening and why at all, however, this
did not seem to happen before the commit 30add3e6b3e3.
